Hello everyone, I'm designing a refrigeration machine, where inside it is mounted a fridge compressor (model you po this http://www.directindustry.it/prod/c...essore-frigorifero-ermetico-30988-281879.html), in this compressor there are 3 tubes, 1 of mandata, 1 of suction, and 1 of refrigerated liquid circuit filler. I'm sure what is to be removed, but I haven't found it on the network yet or even on the manufacturer's website, an indication of which are the intake tube, someone knows this type of compressor to give me a safe indication or a link where to find something precise?
I have to do the internal piping and I don't want to miss the links. . .

Thank you.
 
Then... already looked, but there is all voltages, pressures, dimensions (also detailed enough) except for the indication I look for.
 
You need to check the pipe diameters.
the suction tube has the greater diameter, next there is the charge (smaller) and on the opposite side of the suction tube there is the smaller diameter mandata tube.
 
So, I attach a file downloaded directly from the manufacturer's website and properly modified to make me understand.

I circled in red the odds relative to the inner diameter of the tubes. I'm sure only of the load I wrote in red, but in this case it has the diameter equal to another tube.
according to the logic you tell me, of the two remaining the largest one (8.1) is the aspiration and the smaller one (6.5) is the mandate? Am I right? Are you sure? (I ask only for confirmation)

I've been dealing with compressors for the fridge.
I do not find the brochure but in the drawings of the specifications were highlighted the two tubes.
In my case the condenser tube (i.e. the hot one that goes to the serpentine) is the one that has a big cylinder on the tube and it's the left one (compared to the photo of the link) that is on the side of the electrical attachment box. the one to dx is instead that of the evaporator (internal cold fridge plate). the one behind dx is for the filling that is closed
 
I don't know more than fish, unfortunately I have to do this by studying on my own because the only people who might know (I say they could also because all the compressors that sent us had the filling valve on the sx tube, for that I said I was sure, but at this point I'm not sure of anything) are our collaborators who give me summary indications and happen to tell me one thing on the phone, then when all the other machines arrive here. So I don't understand anything anymore... I don't know what to do anymore, because they're gonna have to mount them and they're gonna mount them like this... now how do I adjust that if I call them then they can't answer me? Mah...
I'll call the producers so I'm going to be safe and they'll make a point. . .
 
I'm sure of what I wrote to you because I have a set on which I then made the prototype that has attacks like I told you.
I don't know if it can vary according to the model and brand you use, unfortunately I don't have the references to understand what I used.
 
thank you very much in any case of the advices and suggestions, unfortunately I am getting more and more screwed thinking about the dish with which I have to collaborate.

Thanks anyway. . .
 
... you don't know how much I understand, always dealing with poorly competent people.

Please, anyway!

It's been a couple of years since the last refrigeration plant and I have rusty neurons.
I have to see a few things again, if you want tomorrow I'll take a look and give you an answer.

ti allego the manual of a similar compressor of the danfoss.

as you can notice the intake and charging tubes (in this case from 6.5) can be exchanged, while the smaller one (in this case from 4.9) is used exclusively for sending.

For sure, however, he calls to whom he sold it... And then let us know!
 
well, if you try to apensarci it is very logical that the little one is the mandate since in send the "gas" and liquid and in suction and gaseous and therefore the volume varies
 
downloaded from the site cubigel and reported to gas compressors r134a, however if you look at it also for all others.

Kill...
You can see I looked really bad, I swear I looked for at least a couple of days and I couldn't find anything. . .
I'm sorry if I haven't answered these days but I came back to work today and I didn't read.
thank you very much to all, really very kind.... ;)
